State Sen. Diane Savino (D- Staten Island and Brooklyn) is once again proposing a bill that would make forcible touching, including grinding, a D felony punishable by up to seven years in prison. Now, those crimes are misdemeanors, meaning that perverts can only be sentenced to up to a year in jail.

The senator also proposing that the penalty for public lewdness be raised from three months in jail to one year in prison.

“Without tougher penalties in place, serial offenders will continue to victimize passengers on the train and this issue must be taken seriously,” Savino said, citing NYPD figures that show sex crimes such as forcible touching and public lewdness on the subways shot up by more than 51 percent from 2014 through the end of 2016.

“Subway grinding and lewdness are serious sex crimes meant to threaten and humiliate victims,” she said.
